Abstract

A personal dosimeter for collecting a quantity of a gaseous contaminant in proportion to its average ambient concentration over the time of collection consists essentially of a closed receptacle containing a gas-collection medium, a channel-containing diffusion device forming a part of the boundary of the receptacle and a porous, hydrophobic film in contact with the interior side of the barrier. After use, the gas collection medium is removed from the receptacle for determination of the contaminant.
